JOHN E. MARSDEN, OF IHILAIDEL'Pll-IIA, PENNSYLVANIA.

WINDOW-REGULATOR.

Application filed June 18, 1914.

75 all trim/n it may concern.

Be it known that I, Joux E. Mausnns, a citizen of the United States, residingin the citv of Philadelphia, county of Philadelphia. and State of Pennsylvania, have invented a new and useful \Vindow-Regw later, of which the following is a specification.

.\I v invention resides in means. for regulating the position of a window, and more particularh a vehicle window in the door of a carriage, automobile or the like. And my invention resides further,-in means for locking the window in any of its positions.

For an illustration of one of the forms my invention may take reference is to be had in the accompanying drawings, in which:

I igure 1 is a side elevational view, partially in section, showing an automobile with its door havingg, a window operated in accordancewith my invention.

Fig. 2 is a vertical sectional view through the window and door, some parts in eleva-- tion.

Fig. is a vertical elcvational view of the window and its ope 'ating means, some parts in section, with the inner sideof the door removed.

Fig. l is .a side elcvational view, some parts in section. on enlarged scale, showing the operating handle and locking means.

Fig. is a vertical sectional view, some parts in elevation, of the spring counterbalancing means and one form of chain adjostingmeans.

-Fig. (3 is a front elevational view of a modified form of means for adjusting the chain.

Fig. 7 is a fragmentary sectional view through the window glass and its associated parts.

Fig. 8 is a fragmentary sectional view through the. glass showing means of attachin}: the same, to the. operating chain.

Th window pane of glass 1 has on its vertica; sides the channel-shaped metallic members 2 which slide vertically in the metal channels 3 carried by the outer half 4 of thedoor or frame, the inner half 5 of the door or frame being visible in Fig.1 and being attached to the member -l by any suitable means. In each of the channels 5 ii-a preferably disposed a strip 6 of felt or the like to cause-smooth or silent Specification of Letters Patent.

movement of the window in the guiding members 3.

Across the bottom of the window glass 1 is a channel-shaped member 7 having in its opposite sides at 8 a ertures in which engage the fingers 9 o the member 10, embaciug member 7. To the member 10 is secured the member 11 which is attached to the sprocket chain 12. This chain 12 passes over the sprocket wheels 13 and 14,: i

the iOl'll'lCl centered upon the pin or shaft 15 carrying the member 16 having a square hole fitting the squared end 17 of the shaft 15, such squared end 17 being, riveted over as indicated at 18 to hold the member 16 in place. Carried by the member 16 are the pins 19 passing through holes in the sprocket wheel 13-and adapted to engage in holes 20 in the member 21 secured to the door member 5 and forming the bcaring'22 for the rotatable shaft 15 'hieh also passes through the member 23 secured to the memer a. suitable material. is secured to the shaft 15 outside of the collar 25.whieh is adapted to move in the countersink 26 in member 23. To the member is pivoted the grip or handle 27 by which the door may be pulled shut. ()n the inside of the member 5 is secured a spring- 28 which tends to thrust the member 16 and attached parts toward the left, as viewed in Fig. 4, to enter the pins 19 into the holes 20, of which there may be a series disposed in a circle in the member 21.

The other sprocket wheel. 14 is secured by rivets or screws 29 to the wall 30 of the metallic casing 31, the sprocket wheel 14- and the casing 31'being rotatable upon the non-rotatable shaft 39. secured at its end 33 in the member 34. A spiral spring 35 has its one end 36 secured to the shaft 32 while its olherend is secured to the casing 31.

The screw threaded bolt 37 extends freely through the lug 38 on member 34 and carries on its upper end the nut or collar 39, so that the bolt 37 may rotate freely with respect to member 34.- without substantial lonitudinal play with respect to member 34'. gtitlllm'i to the door member is a bracket 40 which is screw threaded to receive the bolt 37, and a lock nut 41 is threaded upon bolt 37. The lower end of bolt 37 is squared at -l-2.to receive a. socket or other wrench be raised or lowered with respect to stationary member 40 thereby ermitting bodily movement of sprocket W eel 14, casing 31 and attached parts to stretch th chain 12 to the desired tension. 7

The operation is as follows:

\Vhen it is desired to lower the window, the operator resses inwardly to the right, as viewed in Figs. 2 and 4, upon the handle 24, removing ins 19 from holes 20, whereupon the han le 24-is rotated, thus rotating the sprocket wheel 13 which drives the chain 12 which in turn drives the sprocket wheel 14. And the window .1 being attachedby member 11 to the sprocket chain 12 the window will be lowered. Upon release of inward pressure upon the handle 24 the sprin 28 will restore the parts to the position siiown in Fig. 4 bringing pins 19. into other holes 20, thus locking the window in its newly adjusted position.

When the window 1 is lowered the sprocket wheel 14 drives the casing 31 there'- by winding up the spring which, when it is desired to raise the window, assists in raising the window, and acts as a counter balance therefor.

In Fig. 6 is shown a modified means for adjusting the tension on the chain 12. Here the sprocket wheel 14 and casing 31 are pivoted uponthe shaft 32 secured non-rotatably to the member 34 on the end of the lever 43 pivoted at 44 to the door member 4. A bracket secured to the door member 4, is screw threaded to receive the bolt 37 provided with lock nut 41, the bolt 37 being .freely rotatable in the car 45 on the outer end of lever 43,'a collar 46 being secured upon the upper end of bolt 37 and a spring 47 intervening between the collar 46 and car 45. By turning the bolt 37 the lever 43 will be shifted on its pivot 44 to move the shaft 32 upwardly or downwardly as required to put the desired tension upon. the sprocket chain 12.

Obviously in place of the sprocket chain 12 may be used a belt or other equivalent device.

What I claim is:

1. The combination with a window, of n means for moving the same coinprisin a .'mmber having locking notches, a member.

e sprocket gitiudinal-ly movable shaft, a stationary carried by and secured against rotation with respect to said shaft, said shaft carrying said wheel and extending therethrough, a locking pin carried by said second named member and extending throu h said wheel and adapted to engage in sai notches, and a spring engaging the end of said shaft and opposing withdrawal of said pin from said notches.

2. The combination with a window, of means for movin the same comprisin a window driving wieel, a rotatable and ongitudinally movable shaft, a stationary member having locking notches, a member carried by and secured against rotation with respect to said shaft, said shaft carryingsaid'wheel and extending therethrough, a locking pin carried by said second named member and extending through said wheel and adapted to engage in said notches, said pin forming a driving connection between said member and sa1d wheel.

' 3. The combination with a window, of

means for movin the same comprising a window driving w eel, a rotatable and longitudinally movable shaft, said driving wheel disposed in fixed angular relation with respect to said shaft, a stationary member having lockin notches, a member carried by andsecure against rotation with respect to said shaft, and a locking pin carried by said second named .member and. adapted to engage in said notches.

4. The combination with a window, of means for movmg the same comprising a window driving wheel, a rotatable and lon affixed-my signature in the presence of the two subscribing witnesses.
